short and quite hot, so mutexes just cause more overhead due to frequent
rescheduling than waiting for the spinlocks does. The free and clear queues
are additionally protected by a R/W lock, which is mostly read-locked, save
for rare cases like allocating page runs.
The total -j8 Haiku image build speedup is marginal. The kernel time drops
about 8%, though.

that causes a locking order reversal (condition variable lock <-> system
profiler lock) and thus a potential deadlock. Instead we use the thread
blocking API directly. Fixes#5229.

I had to uptade the catkeys as Travis tool has trouble keeping up with changes in the repository (most importantly, cpufrequency fixes and mail sentance casing). I hope nothing was lost in the process.
Travis, if you read this, I had to load the catkey files in vim and save them back to get them linked correctly by the buildtools. I suspect some line ending problem or something alike. Also, your fingerprint computation seemed wrong in most cases.

- Haiku doesn't like the ethernet maximal frame size to be set to 0. This drops the CPU usage and some calls to read/write are now occuring.

* Used add_debugger_command_etc() and added more verbose usage message.
* Added option "-m" which iterates through all address spaces and finds out
which virtual pages are mapped to the page.

device path + child partition name. When a "raw" device is unpublished the node
removal notification triggers the partition and child partitions to be
unpublished/removed. Since in that case the "raw" node is already unpublished
trying to resolve it in devfs_unpublish_partition() again to unpublish the child
partitions would fail, leaving the child partition nodes behind. When a new raw
device would then become available publishing its partitions would fail because
of these left behind nodes, causing bug #4587. Seeing that this code is more
compact and straight forward anyway I don't quite see why it was changed in the
first place.

LockAllSourceCaches()) and moved it to the beginning of the file.
* Removed sMappingLock and adjusted the locking policy for mapping/unmapping
pages: Since holding the lock of the affected pages' caches is already
required, that does now protect the page's mappings, too. The area mappings
are protected by the translation map lock, which we always acquire anyway
when mapping, unmapping, or looking up mappings.
The change results in a -j8 Haiku image build speedup of almost 10%. The
total kernel time drops almost 30%.
